Much of the heavy lifting is also done by the assignment of numbers and colors to indicate the impact of the experiment on a hypothesis. That’s much easier to grok as a whole than plain text. I can also easily make quick judgments from the chart that are much more difficult to do from a review paper, such as “later experiments generally oppose this hypothesis, and only early experiments strongly support it” (among those in the chart, of course).
